StringBuffer(字符串加减,同步,性能好) StringBuilder(字符串加减,不同步,性能更好) StringBuffer 和StringBuilder方法一样,区别在同步 方法: append() //增添 insert() //插入 delete() //删除 replace() //替换 substring()//求子串 length() //字符串实际大小 capacity() //字符串占用空间大小 trimToSize(...
toString(); // 将StringBuilder内容转换为String System.out.println(csrContent); // 输出CSR文件内容 1. 2. 步骤4: 输出结果 最后,您可以将读取的内容输出到控制台,或者进一步处理这段String数据。 // 这里已经在步骤3中输出了csrContent 1. 结论 通过以上步骤,您可以顺利地将CSR文件读取为String格式。在...

String、StringBuffer 和 StringBuilder 是 Java 中常用的字符串类型,它们的区别主要在于可变性、线程安全性和性能方面。 String 类型是不可变的(immutable),也就是说,一旦创建了一个 String 对象,就无法再修改它的值,任何修改字符串的操作都会创建一个新的 String 对象。这是因为 String 类型的对象在内存中是以常量...
